CeCILL-C FREE SOFTWARE LICENSE AGREEMENT

Notice

This
Agreement is a Free Software
license agreement that is the result of
discussions between its authors in order to ensure compliance with
the two main principles guiding its drafting:

firstly,
compliance with the principles governing the distribution of Free Software:
access to source code, broad rights granted to users,

secondly, the election of a governing law, French law, with which it is
conformant, both as regards the law of torts and
intellectual property law, and the protection that it offers to
both authors and holders of the economic rights over software.

Preamble

The purpose of this Free Software license agreement is to grant users the
right to modify and re-use the software governed by this license.

The exercising of this right is conditional upon the obligation to make
available to the community the modifications made to the source code of the
software so as to contribute to its evolution.

In consideration of access to
the source code and the rights to copy,
modify and redistribute granted by the license, users are provided only
with a limited warranty and the
software's author, the holder of the economic rights, and the
successive licensors only have limited liability.

In
this respect,
the risks
associated with loading, using, modifying and/or developing or
reproducing the software by the user
are brought to the user's attention,
given its Free Software
status,
which may make it
complicated to use,
with the result that its use is
reserved for developers and experienced professionals having in-depth
computer knowledge.
Users are therefore encouraged to load and test the suitability of the
software as regards their requirements in conditions enabling the security of
their systems and/or data to be ensured and, more generally, to use and
operate it in the same conditions of security. This Agreement may be freely
reproduced and published, provided it is not altered, and that no
provisions are either added or removed
herefrom.

This
Agreement may apply to any or all software for which the holder of
the economic rights decides to submit the use
thereof to its provisions.

loss of profits, operating loss, loss of customers or orders,
opportunity cost, any disturbance to business activities) or any or
all legal proceedings instituted against the Licensee by a third
party, shall constitute consequential loss and shall not provide

Article 9 - WARRANTY

9.1 The
Licensee acknowledges that the
scientific and technical
state-of-the-art when the Software

distributed did not enable all possible uses to be tested and
verified, nor for the presence of
possible defects to be detected.
In this respect, the Licensee's attention has been drawn to
the risks associated with loading, using, modifying and/or
developing and reproducing the Software
which are reserved for
experienced users.

The
Licensee shall be responsible for verifying, by any or all means,
the suitability of the product for its requirements, its good working
order, and for ensuring that it shall not cause damage
to either persons or
properties.

9.2 The Licensor
hereby represents, in good faith, that it is entitled to grant all
the rights over the Software (including in
particular the rights set
forth in Article 5).

9.3
The
Licensee acknowledges that the Software is supplied "as is"
by the Licensor without any other express or tacit
warranty,
other than that provided for in Article
9.2 and, in particular,
without any warranty as to its
commercial value, its secured, safe,
innovative or relevant nature.

Specifically,
the Licensor does not warrant that the Software is free from any
error, that it will
operate without interruption,
that it will be
compatible with the Licensee's own equipment and
software configuration,
nor that it will meet the
Licensee's requirements.

9.4 The
Licensor does not either expressly or tacitly warrant that the
Software does not infringe any third party
intellectual
property right
relating to a patent, software or any
other property right.
Therefore, the Licensor disclaims any and all liability towards the
Licensee arising out of any or all proceedings for
infringement that may be
instituted in respect of the use, modification and redistribution of
the Software. Nevertheless, should such proceedings be instituted
against the Licensee, the Licensor shall provide it with technical
and legal assistance for its defense. Such technical and legal
assistance shall be decided on a case-by-case basis
between the
relevant Licensor and the Licensee pursuant to a memorandum of
understanding. The Licensor disclaims any and
all liability as
regards the Licensee's use of the
name of the Software. No
warranty is given as regards
the existence of prior rights
over the name of the Software or as regards
the existence of a trademark.

Article 10 - TERMINATION

10.1
In the event of a breach by the
Licensee of its obligations hereunder, the Licensor may
automatically terminate this Agreement thirty (30)
days after
notice has been sent to the Licensee and has remained ineffective.

10.2 A
Licensee whose Agreement is terminated shall no longer be authorized
to use, modify or distribute the Software. However, any
licenses that it may have granted prior to termination of the
Agreement shall remain valid subject to their having been granted in
compliance with the terms and conditions hereof.

paralysis following a virus attack, intervention by
government authorities, natural disasters, water damage,
earthquakes, fire, explosions, strikes and labor unrest, war, etc.

11.2 Any failure by either
Party, on one or more
occasions, to invoke one or more of the

11.3 The
Agreement cancels and replaces
any or all previous agreements, whether written or oral,
between the
Parties and having the same purpose, and constitutes the entirety of

be effective as between the Parties
unless it is made in writing and
signed by their duly authorized representatives.

the event that one or more
of the provisions hereof were to conflict with a current or future
applicable act or legislative text, said act or legislative text
shall prevail, and the Parties
shall make the necessary
amendments so as to comply with
